| Abstract: |
| In order to cope with the rapid increase of distributed photovoltaic penetration rate, building a flexible interconnected distribution system is an important means. A distributed planning method for multi-region flexible interconnected distribution system based on soft open point(SOP) is proposed to realize the coordinated optimization configuration of SOP, distributed photovoltaic and energy storage in multiple interconnected distribution networks. The planning model of the flexible interconnected distribution system is established with the goal of minimizing the annual comprehensive cost. A distributed optimization model is constructed by decoupling multiple distribution networks from the multi-port SOP. The model is transformed through convex relaxation and linearization techniques, and is solved by using the prediction-correction-based alternating direction method of multipliers. The effectiveness of the proposed method is verified through numerical example. |
